IMTPRovE-MENT iNNAlL-MACHINES.

The Schedule referred to these Letters Ilatent and `:halting-.part of the same.-

the accompanying drawing making a part of this specification, 1in whichr j Figu'rel isa sectional elevation;v

Figures 2 and 3 are elevations vof opposite ends of the machine..` r V Figure 4 is a side elevation ofthe two 'quadrantblocks, showing theconcentric' cutting-edges, and, lin

. dotted lines, the eccentric faces. kr ",Fignre is 'a lplanofthe periphery of one of the quadrant-blocks; and j Figure 6 is' an` enlarged lsectional elevation of one oflthetqnadi'antfblocks. i

This ,invention relates` to a machine in which `a heated `ironfrodis introduced into grooves formed crosswiseof the peripherieisof two adjacent quadrant' blocl'rs, the. rod being ,partlyfiathe Agroove of each `blockpwhich blocks, after the introduction of the rod, receive a 'rolling motion in-opposite directions, while y but ot course ro the rod is; held in the sameposition, 4 tating 'from the motiomof the said'yquadrant-blocks, from which itresults thatthe rod is `compressed hetween the peripheriesof said blocks, which gradually approach eachother asgthe'bloeks rotate, drawing the rodont thinner until it is ofthe size of the nail de sired until the 4two dies, each with the` impression of one-half ofthe nail-sunk in its face, formed crosswise` of the blocks, come opposite each other by the rotation -'of the blocks, after which the blocksare drawn to# gather, and by means of knife-edges on the blocks and onl the outer edge of one of the dies, that part of the rod" that is in thedies is cut offfrom the rest, and becomes a perfect nail.

Referring to the drawingj A `A isthe flaming, in'two parts, one on each side of the machine, each consisting of va vertical casting, with suitable strengthiug-webs and base-plate, and ,each casting provided l with a wide-vertical slot nearly its entire height,` in which slot,

.quadrantsmandp Near the running across the said vertical slot,

'is a strong rail, c, v its upper surface `forminga track shaped like anioverted-V, Aon each of which tracks rolls one'of the two grooved rollers or wheels f. y

. The said rollers areonthe outer ends of the jourthe two sidesf which-act. as guides, slide the two journal-boxes! and o of thel base of each side-framingand cast with it,

Similar journals extending from the lower ends of said toggle-lever, enter and are supported in horizontal boxes formed in the cross-bars h, one at each side 'oi' thel lever g.

Each one of the said cross-hars is connected by a pail'v of rods, fi, with a cross-bar, lc, bolted t'o the upper side of andsupporting the journal-box l, Whose ends are ygroovedso as to lit the guides ,on each side ofthe Vslot in the framing,[and enable it to slide up and down always in exactly the same vertical plane.

-The boxes l receive and sustain the journals' that extend horizontally-from each sideof the upper quad- 'rant-bloclr m at the corner of the'lsame, as shown. .The quadrant-block is suspended midway between the guides forming the lsides of the vertical slot aforesaid. The lever gis connected by two levers, n, with boxes tween the legs of each standard A.

Seats j. secured (all at the sar'neheight) to the rods Anotlraised,above/the seatsby the operation of the togglelevers g n.

The boxes o receive and sustain the `journals that extend horizontally from each side ofthe lower quadrant-block p attthe cornerof the same, so that this block, like the other, is suspended midway between thestandards A.

side beyond'the adjacent standard A, and bear, outwith cogged sectors fr.

From a box secured between the legs of the standard A, next to the coggcd sectors r, extends horizontally, midway between the projecting journals, a shaft that bears a collar, t, armed on opposite sides with cogged sectors gearing into r.

To thesame shaft, outside the collar: t, is attached an arm, c, the outer extremity 'of which, bya rod, w,

,and is connected with any suitable motor` 4 The lower end of the connecting-rodar is jointed to aconne'cting-rod, z, that has 'its pivotin the bed-piece. On the rim o't' the Camry rests an arm, al, which is rigidly attached at its inner end to the toggle-lever g. To the front standard A, between :the legs ot' the same is sedured, which cross-bar has a central, orifice, c', throughwhich the iron rod from whichY the nails are vformed is inserted.

Grooves d' are cut transversely of the peripheries of the quadrant-blocks, one groove to each block.

Prior to inserting the nail-rod in the orifice c', the

V quadrant-blocks arel brought, by the operation of the o similarl to the boxes l, and likewise placed one befi meneath` the boxes o, serve -to support thelatter when.

' The 4journals of both quadrant-blocks extend at one side of the latter, iixed collars q, which .are armed is connected witha cam-groove, ai, in the eccentric y, whose shaft is mounted in the bed-piece of' the machine,

at a suitable height, a horizontal cross-bar, b',

eccentric' y connecting rod w and cogged sectors a* u,

to such a position that the grooves d coincide, and

the knife-edges out into the nail-rod, partially sever? mg it, and the peripheries of the blocks compress it laterally and extend it longitudinally.

The blocks are not curved ou a true arc, but are eccentric, so that, as they rotate1 their peripheries gradually approach eachother and reduce the size -ol' that part ot" the nail-rod that is between them more and more, the nail-rod, it being understood, remaining stationary, but ot' course rotatingy e Near the opposite corners of the quadrant-block from the grooves d, transverse dies f' are placed,'be tween which the partially-formed nail projects when the dies reach it both at the same time. Previous to this the nail .remains cylindrical in shape, but the dies f are of a form to make the nail four-sided.

Just as the nail enters between the dies the eccen tric y raises the'arm a', and thereby causes the togglelevers g n, which up to this time have stood inclined toward the eccentric, to assume a perpendicular position, the rollers f running' horizontally forward toward the center of the rail c. This movementraises the boxes o and with them the lower quadranlblock, and at the same time depresse's the boxes h.

The latter, as they descend, draw down with them, by means of the rods i, the boxes l, and consequently the upper quadrant-block. Thus the two quadrantblocks are drawn toward each other, and their mutual approach continues until the knife-edge on one of the dies aforesaid has severed the nail-blank, and the latter is fully pressed.

That part of the cam-groove a: in the eccentric y through which the pin ol the connecting-rod w travels during the time of the movement of the quadrant-blocks toward each other, is formed concentric with the axis of the eccentric, in order that there may be no rotation of the blocks while they are traveling vertically By the time the cutting and pressing operations are completed the eccentric y begins to reverse the ino- Ition of the quadrantblocks, and also to lower the arm a', which movements are continued until the grooves'` d once more coincide so as to be ready to receive am other blank, and the toggle-levers g n again are in- -clined backward, the boxes h and l raised to their y form a oollar on the nail-blank as the quadrant-block rotates, which collar, by the action of suitable cavities in the dies ff, is formed into a head at the same time the rest of the nail is pressed.

. The article, therefore, that drops out of the lower dies f' as the block p rotates downward, is a perfect nail.

Having thus described my invention,

What I claim as new, and desire to ,secure by LettersPatent, is-

1. lhe combination of the quadrantblocks provided with transverse grooves d', the dies f', audknife-edges m1, substantially as shown and described. v

2. The combination ofthe quadranoblocks, provided with sliding-boxes, thek toggle-levers g n, connectingrods i, arm c', and eccentric y, as specified. l

3. The combination of the quadrant-blocks, collars q t, cogged sectors fr u, crank o, connecting-rod w, and eccentric y, as described.

4. The arrangement of the toggle-levers g n, ties c, ribs e, rollers f, and boxes h 0,-as set forth.
